This question already has an answer here:

Sometimes I would wake up and try to unlock my phone and be told that it doesn't recognize my fingerprint and that I HAVE to put my passcode to enable touch id but I thought that only happened when you put your finger on the home button too much and you don't have that finger registered or something. For me as soon as I wake up it says it doesn't recognize me like I already tried it before when I know I didn't and nobody else did either. Does anybody know what's going on?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


See this article on Touch ID. It says:

If your passcode hasn't been used to unlock in six days, and Touch ID hasn't been used to unlock in six hours, you'll need to enter your passcode or password to re-enable it.

So you should expect to re-enter your password around once a week. It's a good idea, because otherwise you might not use your password for months and forget it.
